OP here. While I understand that downgrades from trailers and promotional material is normal (and I can understand why it happens), in this case the effects don't appear to be unstable. In fact, some users report better performance with the "mod".

Now, the main conspiracy theory around is that console manufacturers asked Ubisoft to downgrade the game as their machines couldn't achieve a result as good the PC. Which is particularly bad as they are barely one year old.

I don't aim to start a flamewar or a a global outrage, but I want to know HN's opinion and what you think is the reasons behind this.
